The manufacture of PTFE BESTEFLON

Cov txheej txheem tsim khoom ntawm PTFE feem ntau suav nrog 4 kauj ruam tseem ceeb hauv qab no:

1. kev tsim cov monomer

PTFEyog ib qho polymerization ntawm tetrafluoroethylene (TFE) monomer polymerization ntawm polymer compounds. monomer synthesis ntawm TFE yog thawj kauj ruam hauv cov txheej txheem ntau lawm ntawm PTFE. Tam sim no, kev lag luam feem ntau siv txoj kev electrolytic fluorination los npaj TFE monomer, piv txwv li, anhydrous hydrogen fluoride thiab ethylene nyob rau hauv qee qhov xwm txheej rau electrolysis reaction los tsim TFE monomer.

2. Kev ua tshuaj polymerization

TFE monomer ntawm qee qhov kub thiab siab, ntxiv catalyst thiab solvent, polymerization reaction. Thaum lub sijhawm polymerization reaction, TFE monomer yog polymerized tas li los ua PTFE siab molecular hnyav, qhov kub, siab, catalyst hom thiab concentration ntawm polymerization reaction thiab lwm yam yuav cuam tshuam rau qhov hnyav molecular, qauv thiab cov khoom ntawm PTFE.

3. Kev kho mob tom qab

Tom qab ua tiav qhov kev sib xyaw ua ke, kev kho tom qab yuav tsum tau ua kom tau cov khoom PTFE ntshiab. Kev kho tom qab feem ntau suav nrog kev ntxuav, ziab, tsoo, sieving thiab lwm yam kauj ruam kom tshem tawm cov catalysts, cov kuab tshuaj thiab lwm yam tsis huv kom tau txais cov khoom PTFE cob ntshiab.

4. Cov txheej txheem pwm

PTFE resin particles yog molded nyob rau hauv qee yam mob kom tau txais qhov xav tauPCov khoom TFECov txheej txheem molding suav nrog extrusion, txhaj tshuaj molding, calendering thiab lwm yam, raws li cov kev xav tau sib txawv ntawm cov khoom kom xaiv txoj kev molding tsim nyog. Cov txheej txheem molding kub, siab, ua haujlwm ceev thiab lwm yam yuav cuam tshuam rau kev ua tau zoo thiab zoo ntawm PTFE cov khoom.

Cov khoom siv raw ntawm PTFE

Xyoo 1936, cov kws tshawb fawb Asmeskas tau tshawb pom cov khoom siv polytetrafluoroethylene (PTFE) hauv chav kuaj mob, thiab tam sim no lub ntiaj teb tuaj yeem tsim cov PTFE hauv tsawg dua 20 lub tebchaws, feem ntau yog cov tebchaws tsim kho. Xyoo 1960, Tuam Tshoj tau siv cov thev naus laus zis ntau lawm thiab ua tiav kev tsim khoom, thiab tau dhau los ua tus neeg siv khoom loj ntawm PTFE, uas cov khoom qis dua tau ntau dua li qhov xav tau, tab sis ntau cov khoom siab dua tseem yuav tsum tau vam khom cov khoom xa tuaj ntawm cov tebchaws tsim kho.

Cov khoom siv PTFE raw khoom thiab cov khoom lag luam tam sim no hauv Suav teb feem ntau yog los ntawm Tebchaws Meskas, Nyiv Pooj, thiab cov tebchaws European. Vim yog tus nqi thauj mus los thiab lub voj voog xa khoom, Tuam Tshoj yuav tsum tau xa cov khoom lag luam Nyiv Pooj feem ntau, thiab Nyiv Pooj yuav tsum tau xa cov khoom lag luam PTFE zoo kom tau raws li qhov xav tau hauv tsev rau cov khoom siv siab.

Raws li cov lus tawm tswv yim kawg ntawm cov neeg siv khoom, cov khoom lag luam hauv lub zog kho tshuab ntawm qhov kev siv tiag tiag ntawm cov xwm txheej ua haujlwm, kev tiv thaiv nkag thiab kev ruaj khov kub thiab qis, cov ntaub ntawv xa tuaj zoo dua li cov ntaub ntawv hauv tsev.

Kev yuav cov PTFE tubing zoo tsis yog tsuas yog hais txog kev xaiv cov lus qhia sib txawv rau cov ntawv thov sib txawv. Ntau ntxiv rau xaiv lub chaw tsim khoom txhim khu kev qha. Besteflon Fluorine yas Industry Co., Ltd. tshwj xeeb hauv kev tsim cov PTFE hoses thiab cov raj zoo rau 20 xyoo. Yog tias muaj lus nug thiab xav tau, thov koj xav sab laj nrog peb kom tau txais cov lus qhia ntxiv.
